Scrall change log

Here is where significant changes to the Scrall Specification are logged.

If you have been reading Appendix B of Models to Code, you may notice a few variations in the online specification. This page is a good place to look for these differences.

July 9, 2017 / Replaced the return keyword with the =>> symbol for the return action used inside a called activity.

July 7, 2017 / Added the system defined _subclass name method which returns a value for an enumerated type generated for a specified generalization. This can be used in conjunction with the case statement so that a superclass instance can switch actions based on its current subclass instance. See the case switching section.

July 3, 2017 / Added a case action block for switching on enumerated values.

June 21, 2017 / In Models to Code the swap action is described. It has been replaced by the & action which serves the same purpose.
